【正文】 Abstract Abstract All bodies has its own infrared radiation characteristics. For studying the various objects of infrared radiation, people use ideal─absolute blackbody radiation body (hereinafter referred to as in bold) the benchmark. Can absorb all the incident radiation and not the reflection of the object is called in bold. Good absorber must have also been good radiation body, so the blackbody radiation efficiency is highest, the radiation rate than a 1. Any real objects of radiation emission quantity and the same temperature blackbody emission of quantity of launch than, called the object than radiation rate, its value is always less than 1. The object than radiation rate, and the material object types, characteristics, temperature, surface other factors, such as the wavelength. According to the topic request, we design a simple infrared obstacle avoidance of the car. The circuit design basically has the following four modules: sensor module (infrared transmitter and receiver), control module (AT89S52 devices), executive module (servo motor), power supply module. Sensor module mainly through to the left and right of the infrared sensor signal, respectively the collection, transfer to the control module. Control module to the acquisition of signal processing, make more the control after 沈陽化工大學(xué)學(xué)士學(xué)位論文 Abstract signals to execute module. The software design includes basic car to walk, walk, the bination of infrared obstacle avoidance program design, such as walking strategy improvement, through to the infrared signal processing to achieve the best car walk path. Cooperate with the right software design, the car can in the design of the track accurately and rapidly finish walking task. Keywords: infrared。 sensor 沈陽化工大學(xué)學(xué)士學(xué)位論文 目 錄 目 錄 第一章 緒 論 ............................................ 1 紅外線研究背景 ........................................ 1 第二章 紅外避障機器人的設(shè)計方案 ............................ 3 主要設(shè)計任務(wù) .......................................... 3 任務(wù)分析與方案設(shè)計 .................................... 3 任務(wù)分析 .......................................... 3 方案設(shè)計 .......................................... 3 第三章 硬件電路設(shè)計 ...................................... 5 .................................... 5 紅外發(fā)射二極管的選擇 ............................... 5 紅外接收器的選擇 ................................... 7 控制電路設(shè)計 ......................................... 10 人機接口單元 ......................................... 11 LCD1602 顯示 ...................................... 11 串口電路設(shè)計 ...................................... 12 執(zhí)行電路設(shè)計 ......................................... 13 伺服電機 ......................................... 13 伺服電機的信號控制 ................................ 14 電源電路設(shè)計 ......................................... 14 沈陽化工大學(xué)學(xué)士學(xué)位論文 目 錄 ............................................. 15 第四章 軟件設(shè)計 ......................................... 16 基本行走命令 ................................... 16 基本巡航動作 ...................................... 16 勻加速 /減速運動 ................................... 17 紅外探測 ............................................. 19 測試紅外發(fā)射探測器 ................................ 19 紅外發(fā)射程序 ...................................... 20 .......................... 22 第五章 結(jié)束語 ............................................ 23 結(jié)論和展望 ........................................... 23 致 謝 ................................... 錯誤 !未定義書簽。而在機器人在復(fù)雜地形中行進時自動避障是一項必不可少也是最基本的功能。我們的自動避障小車就是基于這一系統(tǒng)開發(fā)而成的。伴隨的科技水平的提高，機器人的能夠使用的傳感器種類也越來越多，其中紅外線傳感器已經(jīng)成為機器人自動行走和駕駛的重要部件。紅外傳感器的典型應(yīng)用領(lǐng)域為自主式智能導(dǎo)航 系統(tǒng)，機器人要實現(xiàn)
